When I hit the Midtown Scholar I picked up a couple of books to read: Locke's "Second Treatise on Government" and Hofstadter's "Gödel, Escher, Bach - An Eternal Golden Braid". I haven't started Locke's book, but GEB is downright fantastic so far.
The funny thing about it though, is that several people recommended it to me, but everyone I've ever talked to has said that they love the book but never finished it.
We'll see how far I get into it. So those sit on the pile of books I'm reading right now, along with rereading a biography on John Adams, two books by historian Garry Wills ("Inventing America", and "A Necessary Evil"), and "The Virtue of Selfishness" by Ayn Rand.
Reminds me of the time in Star Trek: TNG, when Picard took "Ethics, Sophistry and the Alternate Universe by Ving Kuda" on his vacation and Riker commented "Not exactly light reading", but Picard replied "To each their own".
And, by the way, if the above does not completely confirm that I'm a geek, well then, I don't know what will.

I don't know if you've done a review of it, or if it has been on your "must read" list...but read The DaVinci Code, by Dan Brown. I'm only halfway thru it, but it is amazing, one of the best books I've read in a long time, and it justifies its' rave reviews. I'm just wondering about the accuracy of the material, the religious history and so forth, that he writes about in it. That would be great if so...this book just blows my mind.
